@@sexus400what if the check engine like isn’t pausing

[@neitodesu]

​@@SarrioVisionaryif either light continuously blinks with no pause, that means you have no codes

[@sexus400]

yeah, what the other comment said. if it is constant blinking. you have no codes👍🏻

Did you fix the issue? If you did, what was it?

[@sexus400]

no I never did. car never ran weird so I just left it. I plan on fixing it this winter tho. I think it was a vacuum modulator or something. I cant remember what it was called.

[@adamnrt4232]

Does this work for any codes in the system ? like not just engine/transmission codes ?

[@sexus400]

what other codes would you be looking for?

[@adamnrt4232]

@@sexus400 all my power windows work intermittently, when one works they all do. usually once I crank it up they’ll work but after a while they all stop, no noise or anything coming from the regulator and I’ve been thru about 3 window switches. I have some issues with my gauge cluster aswell not sure if that’s related but I doubt it. any ideas ? I thought damaged wires but I chased the harness all the way around

[@sexus400]

grounding problem somewhere would be my guess. common problem especially for those gauge clusters. usually have to send them in somewhere to get fixed. I wouldn't be surprised if it is a similar problem with the windows but im not sure. these cars are too old to get any other codes or anything like that besides engine and transmission. idek if new cars would tell the problem on stuff like that haha
